...
A conforming implementation shall produce at least one diagnostic message (identified in an implementation-defined manner) if a preprocessing translation unit or translation unit contains a violation of any syntax rule or constraint, even if the behavior is also explicitly specified as undefined or implementation-defined. Diagnostic messages need not be produced in other circumstances.
Assuming a comforming conforming implementation, eliminating diagnostic messages will eliminate any violation of syntax rules or other constraints.
Exceptions
Compilers can produces produce diagnostic messages for correct code. This is permitted by C99 which allows a compiler to produce a diagnostic for any reason it wants. It is often preferable to rewrite code to eliminate compiler warnings, but in if the code is correct it is sufficient to provide a comment explaining why the warning message does not apply.
